SCIENCE is a part of EVERYONE'S everyday life.

As my old professor Carl Sagan said so often, 'When you’re in love, you want to tell the world.’ And I base my beliefs on the information and the process that we call science. It fills me with joy to make discoveries every day of things I’ve never seen before. It fills me with joy to know that we can pursue these answers. It is an astonishing thing that we are — you and I are one of the ways the universe knows itself.

You and I are made of stardust. We are the stuff of exploded stars. We are therefore, at least 1 way that the Universe knows itself. That, to me, is astonishing.

There are two ways to be rich: to have more or need less. It's estimated that we squander about 30 percent of our energy leaving the lights on, the refrigerator door open, and so on. Then there is the enormous amount of food that we expend huge amounts of energy to raise and then throw away.

The most serious problem facing humankind is climate change. All of these people breathing and burning our atmosphere has led to an extraordinarily dangerous situation. I hope next generation will emerge and produce technology, regulations, and a worldview that enable as many of us as possible to live happy healthy lives.

There really is no such thing as race.

There are two questions that get to us all: Are we alone in the Universe? And, where did we come from? For me, science provides a much more satisfactory way to seek answers than does any religion I've come across. With that said, the universe is mysterious and wonderful. It fills me with reverence for nature and our place among the stars; our place in space.
